would y'all please recommend a .15 RC airplane engine?

i found a set of sig tri-star plans i can build from, and that's the
recommended size engine... and of course it's the size i don't have. ;-)

You could go to www.mecoa.com and buy a Cox .15. They are one of the
hottest .15's ever made.

The nice folks over at http://www.thundertiger4u.com not only stock the
excellent Thunder Tiger GP-15 .15 2-stroke motor, but they have good
availability on spare parts as well:

I always try to support my local hobby stores, but they don't carry very
much from Thunder Tiger.  I've ordered several things from
www.thundertiger4u.com in the past, and always been happy with the service
and value.  They even tracked down a particular replacement motor mount for
me from a favorite old ARF of mine and added it their catalog at my request.

Thunder Tiger makes great stuff, and I'm really glad I've got a good source
to find it!

The TT .15 that Ed recommends is what I recommend. It is light, no ball
bearings to hassle with and it runs great.

I bought two of these and two plain bearing Enya .15s a while back when
Sheldon's Hobbies was selling out their Enya engines.

I like TT GPs, too.

But I'd recommend a .25 GP for your plane.

Or a ball-bearing .19.

A little extra power never hurt anybody.

I had a TT .25 in a SIG Wonder.  It was a very nice
combo.  The mid-air that took its life wasn't the
fault of the engine.

Prior to the .25 GP, I had used a Magnum .15.
Even when it was working right, it wasn't as much
fun to fly as with the .25.

Yes, weight and wing loading went up.  I also had
rudders on the thing, so that added another couple
of ounces.  It was nothing like the 50 oz. electric
version that I read about being flown successfully.

YMMV.

i have an OS .25FX.
it's a bit much for the tri-star, but thanks for the suggestion

otoh, i could scale the tri-star up to .25 size... hmmm

No.  If you scale up the plane, then it's a candidate
for a TT .40 GP or OS .40 FP or a .32 or .36.  :o)

Magnum .15 XL is a nice little screamer and reasonably priced.

I've had mixed luck with Magnums in general, but I've had a few of the
.15XLs and they've all performed great.

Obvious choice would be the OS LA 15 for about $60.
Another one I like (I have 2) is the Norvel BigMig 15 also for $60.

I like the little OS, but the price is ridiculous.

I'll stick with the $44 and change TT .15. Not to mention the fact that the
OS LA series engines are the ugliest engines in existence, right next to
Saito engines. <G>

How about a clean, hardly run K&B Veco .19  Series 71?  It will blow the
socks of any .15 available today.

I used a Magnum .15 on the Tri-Star.  Need hi nitro content fuel.  I
used some COX fuel I had around.  I forget the size prop I put on it.

The Tri-Star is not high performance, so you really do not need a
hotter engine.

Perhaps, but where would one get such an engine? :)

Personally, for a 0.15 sized plane, I'd probably just go electric.
But that's just me.

I'd go with a Thunder Tiger .25 GP.

Light, cheap, durable (plain bearing), forgiving.

I went from a Magnum .15 XLS to a TT .25 GP in a
Sig Wonder.  I was very happy with the results.

Check out the Mini Fledgling (scroll down)  Built light, a .15 should
haul it OK.  They're fine fliers!  Electric to glow conversions may need
to be beefed up due to the added vibration of a glow engine.

The Thunder Tiger Dragonfly .15 ARF might be a fun choice:

http://www.thundertiger4u.com/thunder-tiger-dragonfly-p-7297.html

It's listed in the trainer section, but by most accounts it's fast and
aerobatic.  It flies more like a stik than a trainer.

That reminds me of my second RC airplane, an H-ray.  It flew very well with
an OS-15 (still in the box of good/old stuff) even with the high weight of 3
channels of a Bonner 8 installed.

But that includes the weight of the dog who is going along for the ride.
Not bad.

The best 15 size plane I ever flew is the Wicked Wanda from the RCM
catalog.  Easy to build, a dream to fly.  It's like a miniature Bingo.
I've built them with both 10 and 15 FP engines, and the 15 is just
right.  This could be the perfect plane.

Another really great airplane was the Caprice 15 ARF that a couple of my
friends had, but that was well over ten years ago and I don't know if
this plane is still available.

I couldn't remember the name of the plane that the Caprice reminded me
of, but it just came back to me.  The Caprice 15 was just like a little
Avistar.

I owned and flew a Caprice 15 in 1994. Its covering was butt-ugly, but the
model flew amazingly well. I first powered mine with an OS .20FP, which
provided infinite vertical.

I then swapped the two-stroke out for an OS FS-20 four-stroke, which turned
out to be just right. Folks were amazed that the little model took off from
our thick grass field and taxied as well as it did, which was perfectly.

I hadn't thought of the Avistar comparison, but that is a good one. I always
thought of it as a mini Hobbistar 60, but it was much more nimble than the
Hobbistar 60, which flies more like a B-36.

I wish they would resurrect the Caprice 15 ARF again, but this time cover
the wings with translucent blue with the remainder being white with matching
blue trim. This model fills a unique niche that lots of folks enjoy. Come
on, Global. Get the lead out!

Robert Reynolds - 16 Apr 2008 18:52 GMT
I agree completely with Ed.  The Caprice dates back to the era of
ARF-o-kote, which was miserable stuff.  The Caprice green color scheme
looked like they had a contest to see who could come up with the worst
design.  But the plane itself was one of the best.

A friend of mine had one of these just a few years ago with the
red/white color scheme, which was only a little better.  A rough landing
tore the landing gear off, and we stuck it firmly in place with a big
glob of epoxy.  As I recall, the front end was none too fuel proof,
either.  That particular plane was old enough by the time he ended up
with it that the wings had tons of tape patches on them, even though it
hadn't had a lot of air hours.  My friend was the one who came up with
the Avistar comparison.  He was an Avistar junkie, so he would know.  He
wanted me to build him a Caprice replica, except with better structure
than the original.  A worthy cause, I think.

Anybody want to draw up a set of plans for a Caprice?  There really
aren't a lot of planes available in .15 size.
